you were his wife, you weren’t unfaithful but you were that kind of girl who enjoyed others attention and compliments. you were a beautiful, but that’s now why kakashi fell in love with you, he found you when you were at your lowest and he helped you get out of there that’s why you fell in love with him too. he didn’t like you being this welcome from guys, accepting their compliments, he knew you were just a girl and would never cheat on him but he still got jealous.
